Bug Reports

If a moon phase calculation looks incorrect, please tell us the specific date you tested, your location if relevant, and what result you expected. Phase timing discrepancies of a few minutes are normal due to the complexity of lunar mechanics, but larger errors or wrong phase names should definitely be reported. Screenshots are helpful for tracking down display issues.

Feature Requests

Is there a lunar calculation or moon-related tool you need that MoonCalc doesn't yet offer? We're always looking to expand — past requests that made it into the site include moon sign calculators, eclipse finders, and moonrise/moonset estimators. If you have an idea, let us know. There's a good chance other users are waiting for the same thing.

General Feedback

If the interface is confusing, an explanation is inaccurate, or you'd like to share how MoonCalc helped you plan a night of astrophotography or track your garden's lunar planting schedule, we welcome all messages. Every piece of feedback helps us prioritize improvements.
